How to prefill PayPal email on login form?

Question

I am using PayPal's login (https://devtools-paypal.com/guide/openid) integration script to get consent from my website users. I would like to send email field prefilled on PayPal login page. I tried sending through query string but that doesn't work. Can we do it?

Any help would be much appreciated. Thanks

According to PayPal support team, this feature is not available as of now. They have added my request in the feature list so hopefully we can expect it in future.

If you are using ExpressCheckout you can pass the EMAIL field with this address, however, it will be overridden depending on the browser.

The only option to force an account when logging in is to use AdaptivePayments. You would set senderEmail and they should not be able to change it.
